Why is he feeling this pain?!?

Hi, my boyfriend had a hernia for about six months. He finally got it diagnosed. It was a hernia where the intestine went all the way into his scrotum. A week before the surgery, he started having electric shock-like pain in his thigh. He realized the pain only occurred when he touched his neck/shoulder or when someone rubbed his neck/shoulder. Also, his wisdom teeth are coming in, and one is impacted. He has pain all the way down his neck. He also has bumps on the back of his throat. They swabbed them and tested them. They found nothing. He also has back pain. What is going on? What is the electric pain? What are the bumps? Is the back pain related to the hernia?
